Definitions

  • Roadways are social intra-structure and take charge of most transportation of people and goods. More than 80% of worldwide roads are paved with asphalt pavements, and most of heavy traffic loadings are absorbed into the asphalt pavement layer. Repeated heavy traffic loading and impact making pavement life cycle shortened result to easy pavement damage, or asphalt pavements experience another early damage due to bad pavement construction practice.
  • Asphalt pavements are constructed by paving asphalt concrete mixtures (produced from mixing an asphalt binder, aggregates and fillers at a high temperature) on the roadbed in the order of a base, an intermediate, and a surface layer from bottom to top and then each paved layer is compacted by rollers to finish construction.
  • the important raw materials determining pavement quality is both asphalt binders and aggregates under the assumption of construction well done.
  • aggregate size and gradation cannot be a critical factor due to using almost identical ones, but asphalt binders can affect greatly the pavement quality due to many modifications to be made.
  • the polymer additive to be used for this purpose is called the modifier, and the asphalt binder containing the modifier is called the modified asphalt binder.
  • the modified asphalt binder there exist a lot of differences in physical property improvement of asphalt binder.
  • modified asphalt concrete mixtures modified ASCON
  • high heating 160-170° C., hot mix asphalt
  • medium heating 120-140° C., warm mix asphalt
  • the latter method (the warm mix asphalt production method) is favored in the view of reduction of environmental pollution and saving of energy.
  • production of RAP (Reclaimed Asphalt Pavement)) recycled hot mix asphalt mixing with some virgin materials are recently in the increasing trend to prevent land pollution and to save construction cost.
  • This invention belongs to the technology area of the modified, RAP-recycled (or virgin) warm mix asphalt production including all technologies mentioned above.
  • performance properties of asphalt pavements respond sensitively on magnitude of traffic loading and seasonal temperature variation such that both effects often cause rutting and fatigue cracking of asphalt pavements. That is, under heavy traffic loading, asphalt pavements experience various cracks at low temperatures (at less than ⁇ 10° C.) due to increase of stiffness caused by material contraction. Meanwhile, rutting takes place due to shear flow of materials caused by weakened pavement viscosity at high temperatures (higher than 50° C.). Generally modern economic expansion makes number of automobiles, traffic volume and heavily loaded trucks increased such that pavement problems mentioned above become accelerated and life cycle of existing pavements is drastically shortened. Therefore, major roadways commonly use modified asphalt pavements instead of regular ones to prevent decrease of pavement life cycle.
  • a modifier can be included as a key material element in constructing modified asphalt pavements.
  • the modifier can be constituted from a single polymer (i.e., styrene-butadiene-styrene (SBS), low density polyethylene (LDPE), etc.), but is usually composed of both elastic materials (to resist cracks in the cold winter) and viscous materials (to minimize rutting in the hot summer).

  • PE polyethylene
  • Gilsonite a highly viscous liquid
  • asphaltite solid powder
  • Both containing asphaltenes as a major element are characterized to be rigid and strongly stiffened. These materials have disadvantage of producing early pavement cracks due to strong stiffness.
  • gilsonite as a viscosity thickening agent claimed in 2002-034496 and 2003-004579 cannot be a desirable agent in the view of pavement performance properties compared to better different viscosity thickening agents available.
  • Korean patent 10-2007-0669079 to resolve the above brittle problem, Polyethylene (PE, a general purpose resin) is included together. If more PE are added, brittleness is lessened, but lack of binder adhesion on aggregates is resulted due to no functional groups present in the PE molecule that promotes adhesion.
  • Korean patent 10-2003-005537 epoxy resin and petroleum resin as viscosity thickening agents, and SBS and rubber as elasticity enforcing agents, and in Korean patent 10-2003-0069911, petroleum resin as a viscosity thickening agent, SBS and rubber as elasticity enforcing agents, respectively, are used as compositions.
  • epoxy and petroleum resin have disadvantage of producing early pavement cracks due to strong brittleness, the modifier including those compounds cannot be a good agent.
  • the epoxy resin is economically expensive.
  • waste PE film as a viscosity thickening agent is only used without an elasticity enforcing agent. Even though waste PE film is inexpensive, it is not a good modifier as explained above, and cold winter can cause easy cracks on pavements due to no elasticity present.
  • HDPE high density polyethylene
  • crumb rubber as an elasticity-enforcing agent
  • polymer resins used as a viscosity thickening agent are general resins with common viscosity (i.e., waste PE, HDPE, low density polyethylene (LDPE), Ethylene vinyl acetate (EVA), etc.), not high viscosity. If the regular amount of those polymers is added in making modified asphalt binder, enough viscosity building fails. This brings relatively easy rutting. In the contrary, with the large amount added, a cost problem will be added. Furthermore, polymers that can acquire high enough viscosity at elevated temperatures (i.e., gilsonte, asphaltite, petroleum resin, epoxy resin, etc.) can be brittle at low temperatures resulting to easy pavement cracks.

  • a processing wax by Fisher-Tropsh method called a sasobit wax

  • the EVA resin is not considered as a proper modifier because it shows relatively soft viscosity and is not elastic either at low temperatures.
  • the Sasobit wax as a warm mix additive also helps to make brittleness at low temperatures (cracks) and softening at high temperatures (rutting).
  • the Korean patent 10-1166155 claims a warm mix additive by choosing more than one among processing oil, plasticizer, linseed oil, bean oil and rice oil, and, a modifier by choosing polyurethane (PU) polymerized by reacting with polyols (or polyamines) and isocyanate under catalysts (cobalt type, lead type, phosphorous type). But it has failed to provide polymerization degree in the reaction and physical properties of polymerized polyurethane (PU) whether it can be used as a modifier or not.
  • PU polyurethane
  • the Korean patent 10-1023425 uses more than one among processing oil, petroleum resin and sasobit wax as a warm mix additive, and SBS or water-dispersed acrylic emulsion as a modifier. However, total viscosity of modified asphalt viscosity is still low such that it is expected for the modified binder likely to face rutting problem.
  • Korean patent 10-1023425 use of more than one among rosin, polyethylene (PE), Bunker-C oil and asphalt binder as a warm mix additive, and a mixture of EVA and more than one of SBS, styrene-isoprene-styrene (SIS), LDPE, HDPE, PU chip, ethylene-propylene-diem (EPDM) chip as a modifier are claimed to be used.
  • This patent also shows good crack resistance as using elastic materials like SBS, SIS, PU chip, EPDM chip, but possibility of the pavement rutting problem cannot be avoided due to using EVA, LDPE, or HDPE as a viscosity building polymer that belongs to a weakly viscous general purpose resin.
  • HDPE has a relatively high viscosity leading to better rut resistance, it is a nonpolar (adhesion problem on aggregates) and crystalline (easy crack at low temperature due to contraction) polymer. Small amount failing to increase viscosity should be used.

Such a claim is based on scientific experiments obtained from broad research execution about temperature reduction effect of warm mix additives.

  • Warm mix additives are widely used, but crack-resistant warm mix additives may be unfamiliar because they are introduced first time in this invention.
  • Wax-type additives that usually show a melting point at 80-120° C. are often used as a warm mix additive. These waxes take a role of warm mix additives by drastically decreasing their viscosities above their melting points and by increasing their hardness below their melting points. Hardening by waxes below the melting point contributes to overall material stiffening that has a positive effect of traffic loading supporter on pavements, but has negative effect of local crack evolution that are eventually leading to large pavement cracks. This is mainly due to hardening effect of the wax-type warm mix additive. To avoid this negative effect as well as to enhance crack resistance, a small amount of elastic material can be added to warm mix additives. This additive is called a crack-resistant warm mix additive that contributes to reducing pavement cracks at low temperatures.

  • This invention is characterized to constitute the composition of the virgin or the regenerated highly visco-elastic warm mix asphalt concrete mixture by combining 0.5-20 weight parts of a highly visco-elastic warm-mix modifier, 10-100 weight parts of an asphalt binder, 850-987.5 weight parts of aggregates, 2-50 parts of a filler, and, if necessary, a small amount of anti-stripping agent and anti-oxidant.
  • the virgin or the regenerated highly visco-elastic warm mix asphalt concrete mixture is characteristically produced by heating this composition at 80-180° C. and mixing them in the mixer of an asphalt concrete production plant.
  • the using range of the highly visco-elastic warm-mix modifier is 0.5-20 weight parts.
  • the 0.5 weight part is the minimum amount for manifestation of modifier's effect and being more than the 20 weight part makes production very difficult due to extremely high viscosity.
  • the usage is limited in the range of 0.5-20 weight parts.
  • the using range of an asphalt binder is 10-100 weight parts.
  • the 10 weight part is the minimum amount of asphalt binders to produce the pavement base-layer material by using 100% reclaimed asphalt pavement (RAP) aggregates, and the maximum 100 weight parts implies asphalt binders required to produce the asphalt mastic.
  • RAP reclaimed asphalt pavement
  • most of highly visco-elastic warm-mix modified asphalt concrete mixtures use asphalt binders in the range of 10-100 weight parts.
  • aggregates mean all virgin or all RAP or mixed aggregates of virgin and RAP. Especially, when RAP recycling is demanded a lot in the paving industry for environmental and economic aspect, necessity of RAP-recycled asphalt pavements by using the RAP aggregate is ever increasing. To describe usage of both virgin and RAP aggregates together, the aggregate is composed of 100% by adding the less than 100% virgin aggregates to the less than 100% RAP.
  • the 100% virgin aggregate indicates the one for the 100% virgin highly visco-elastic warm-mix modified asphalt concrete mixtures
  • the 100% RAP aggregate does the one for the 100% RAP-recycled highly visco-elastic warm-mix modified asphalt concrete mixtures
  • the sum of 100% by adding the virgin aggregate % to the RAP aggregate % does the one for the partially RAP-recycled highly visco-elastic warm-mix modified asphalt concrete mixtures.
  • the aggregate distribution becomes from the maximum size of 53 mm to the minimum of 0.001 mm. This size distribution is characterized to consider usage of the 19-53 mm size for most of the base and the intermediate layer, and usage of the less than 19 mm size for most of the surface, the wearing and the mastic layer.
  • the surface layer aggregate distribution for the less than 19 mm can include all grades like dense, rut-resistant, mastic, low-noise porous, bridge surface, SMA (surface matrix aggregate), airport taxi-layer, superpave, gap and an arbitrary grade by a designer.
  • the 850-987.5 aggregate weight part represents solely the aggregate part only out of total 1000 weight parts by excluding all other constituents.
  • filler is added to asphalt binders. When the proper amount of filler is added to a binder, it strengthens asphalt pavements to promote stiffness and crack resistance that reduce rutting and fatigue cracking. Especially, filler is a key material for porous asphalt pavements because it contributes to maintain the original air void not to be collapsed.
  • a filler is characterized to include aggregate powder, limestone powder, furnace slag powder, cellulose fiber, glass fiber, polymer fiber (i.e., polyethylene (PE) fiber, polypropylene (PP) fiber, nylon fiber, etc.), carbon black, fly ash, glass fiber, clay powder, calcium carbonate powder, caustic soda, lime soda, cement, steel-making powder and other fillers. Effect of these fillers can be ignored under 2 weight parts, and, above 50 weight parts, asphalt binder viscosity is increased too much such that production and construction are very difficult to do. Also, stiffness of an asphalt mixture itself increases too much to cause acceleration of pavement cracks by adding excessive fillers. That is why filler use is limited to within 2-50 weight parts.
  • the corresponding asphalt concrete mixture (the highly visco-elastic warm-mix ASCON) claimed above must be produced. Two methods of production exist and either one can be chosen.
  • vinyl-film bags containing a specified amount of the highly visco-elastic warm-mix modifier in the form of fine powder (or particle) are transported to the asphalt plant, and the designed number of bags is dropped into the mixer of the plant already containing specified amount of aggregates and fillers. They are mixed under the warm-mix temperature by spraying the general asphalt binders to produce the highly visco-elastic warm-mix modified asphalt concrete mixture. This production method is called the plant-mix type.
  • the pre-mix production method is to mix asphalt binders and highly visco-elastic warm-mix modifiers in advance to manufacture the uniform highly visco-elastic warm-mix liquid asphalt binders. These are brought to the asphalt plant to spray on aggregates and fillers for production of the corresponding modified warm mix asphalt. Meanwhile, the plant-mix method is to insert asphalt binders, specified amount of highly visco-elastic warm-mix modifiers, aggregates and fillers separately in the mixer of the asphalt plant and mix them well at the warm-mix temperature to produce the corresponding modified warm mix asphalt (WMA). Because both methods are to produce the same modified warm mix asphalt (WMA), either method can be used.
  • the highly visco-elastic warm mix modifier constituted by the above composition can be applied to construct diverse asphalt pavements; in examples, the low-noisy modified warm-mix porous asphalt pavement using the low-noisy porous aggregates; the surface and the base layer of the modified warm-mix general asphalt pavements using the dense-graded or the superpave aggregates; the modified warm-mix RAP-recycled asphalt pavement using mixed aggregates of RAP and virgin or only RAP aggregates; the modified warm-mix bridge surface pavement using the bridge surface aggregates; the modified warm-mix SMA asphalt pavement using the SMA aggregates; the modified warm-mix airport-taxiway asphalt pavement using the airport-taxiway aggregates.
  • the very modifier takes a key role in improving functionality, performance, life-cycle of each pavement mentioned above.
  • Asphalt pavements mentioned above are indicated to be the surface, the intermediate, the base layers of modified asphalt pavements to be paved on the general traffic, the low-noisy porous, the RAP-recycled, the cold and the hot regional, the bridge surface and the SMA roadways, classified as pavement functionality, and major highways, urban and suburban traffic roads, industrial heavy traffic roads, local highways, airport taxiways classified as pavement usage.
  • the environment-friendly modified warm-mix asphalt pavement will also provide reduction of pavement maintenance cost due to the pavement life-cycle extension.
  • FIG. 1 I-Temperature reductions of single & combined warm-mix additives.
  • FIG. 2 II-Temperature reductions of single & combined warm-mix additives.
  • FIG. 3 Elastic effect of the Sasobit-wax containing an elastic material (R).
  • FIG. 4 Elastic effect of a single warm-mix additive (CM) containing an elastic material (R).
  • FIG. 5 Elastic effect of a combined warm-mix additive (CM+HCO) containing an elastic material (R).
  • compositions of highly visco-elastic warm-mix modifiers for the practice (1, 2, 3) and the comparison (1, 2, 3) are listed in Table 1.
  • Each modifier shown in Table 1 is well mixed with a given amount of an asphalt binder at 180° C. for 2 hours to produce a homogeneous modified asphalt binder. Penetration tests are performed at 25° C. for these modified asphalt binders and the measured results are displayed in Table 1.
  • Table 1 shows that the penetration value of visco-elastic warm-mix modified asphalt binders and the Marshall Stability of its asphalt concrete mixture in the practice (of this invention) are turned out to be further better, compared to those values of a general asphalt binder or other modified asphalt concrete mixtures in the comparison.
